Generating a Windows installer for your AIR captive runtime application

I recently wrote a pretty big tuto­r­ial about Adobe AIR, its cap­tive run­time mode, and how to gen­er­ate a Win­dows installer on top of that. It was writ­ten in French and pub­lished on

I then con­tacted the fine folks at Adobe Devel­oper Con­nec­tion and offered to trans­late it to Eng­lish. They accepted, reviewed it, and boom: pub­lished it.

Wether you’re a French or Eng­lish reader, I got you cov­ered. Tell me what you think.

Shrink O’Matic 2

Back in 2008 I would spend some of my Sat­ur­day after­noons sit­ting in a Laun­dro­mat, wait­ing for my clothes to smell good. I quickly real­ized these moments were per­fect to bring my lap­top with me and code. One of the first AIR apps I wrote was Shrink O’Matic, now you know where the name comes from.

It quickly became suc­cess­ful. It now has been down­loaded 168,000+ times, a best-seller of sorts. Except it’s free.

But with suc­cess comes feed­back, and with feed­back comes fea­ture sug­ges­tions. Most of them were included through updates, some of them didn’t make the cut. Prob­a­bly because of me being lazy or because of AIR’s limitations.

Then AIR 2 came out, then I learnt Robot­legs… So I re-wrote it from scratch! Intro­duc­ing Shrink O’Matic 2, the same quick and sim­ple app but with more fea­tures and a nicer theme.

Here’s what’s fresh off the oven:

  • Drop fold­ers onto the app: every image in it (or in its sub-folders) will be shrinked.
  • New “Rota­tion” set­tings pane: either use a spe­cific angle or let the app read your images’ EXIF data and decide what to do.
  • Cus­tom name option: choose exactly what the out­put name will be using your own pat­tern and inject­ing the orig­i­nal file’s name (using $name) and/or its posi­tion in the queue (using $num).
  • PNG files now keep their trans­parency when shrinked.
  • Water­mark: water­mark your images, even choose where to place the overlay.
  • Drop files onto the app while it’s pro­cess­ing, no problemo!
  • No more dimen­sion limits.
  • Shiny new theme!

But! I decided some fea­tures had to go. I removed the “name pre­view” that used to be in the sta­tus bar. I also removed the abil­ity to drop images from web pages. If you need these fea­tures and want them back, make sure to drop a com­ment and let me know!

That’s it, go get it!

MSK view, for iOS and Android

I’ve been work­ing on an app for a French sport hos­pi­tal, designed to browse its msk image library. It’s called “MSK view” and it is avail­able for free in iTunes (iPhone and iPad ver­sion) and in the Android Mar­ket.

Pretty tech­ni­cal stuff in it, not sure every­one will want to install it but hey, there may be some doc­tors out there!

The hos­pi­tal is French but the app is both in French and Eng­lish. Built in Flash Builder with Flex Mobile, Robot­legs and AMFPHP, UI design by Jumo.

Now go show off brows­ing images of “Scapho­trapezial Syn­os­to­sis” or “Rec­tus Femoris intra­mus­cu­lar Haematoma”, what­ever it may be!

Boks is now OpenSource

Boks is one of my most suc­cess­ful apps and this is prob­a­bly not only because of its use­ful­ness, but also because it is free, too. I released it more than 2 years ago and it is still heav­ily downloaded.

The CSS com­mu­nity is really active and fast-moving. When I wrote Boks, Blue­print CSS was one of the most watched and forked project on GitHub which is mostly why I chose to base my UI and logic on it (it still is at the top, by the way). But with today’s CSS3 hype and because of the ever-growing list of CSS frame­works (not going to list them here) I started receiv­ing lots of fea­ture requests.

At first I thought I could wait and han­dle them later, but I quickly real­ized it would need a lot of time, and I defin­i­tively didn’t have it in my hands (or at least not for this project). The idea to Open­Source it seemed obvi­ous and I’ve been slow doing so, but here it is. If anyone’s will­ing to take a look at what I wrote and fix or improve it, do it! Don’t for­get that this has been writ­ten a while back and I wouldn’t re-write it this way (think Robot­legs); I know the code will look crappy to some but hey, we all learn and evolve, right?

I’ve licensed Boks’ source under GNU GPL v3 in order for it to remain Open­Source, but if you have other sug­ges­tions, just tell me.

Signl – A Custom AS3 Signal File Generator

Remem­ber Evnt, the quick and sim­ple UI to gen­er­ate AS3 Event subclasses?

Well, it’s still here but I don’t use it much any­more, since I’m a big fan of Robert Pen­ner’s Sig­nals! So I wrote Signl. It’s basi­cally the same thing, but for Signals.

I know writ­ing Sig­nal classes is an easy task; but, why not make it eas­ier? I hope this helps! Oh, and by the way, it’s Open­Source, just like Evnt was.

Unipasta, a Unicode browser

When writ­ing in French I’m always look­ing for char­ac­ters that can’t be eas­ily typed with a key­board (like œ, for exam­ple). I used to go to for its sim­plic­ity: just go to that page, click on a char­ac­ter and boom, it’s in your clip­board, ready to be pasted!

But I wanted some­thing more powerful/thorough that would remem­ber my fre­quently used char­ac­ters. So I wrote Uni­pasta!


Here’s what you should know about it:

  1. Every input under the selected char­ac­ter (char, code and hex) can be edited and will update each other. Eas­ily jump to any character!
  2. The font met­rics (base­line, x-height and cap-height) are auto-calculated and will help you know where the char lives;
  3. Click on the “More Info” link to jump to and access a lot of details about the selected character;
  4. Every char­ac­ter your click will be auto­mat­i­cally copied to your clip­board, handy!
  5. Use the “Recent char­ac­ters” list to quickly access your favorite ones (lat­est used will always be listed first).

If you think some miss­ing Uni­code blocks are impor­tant to you or if you’d like to add a new char­ac­ter list­ing, just ask for it!

Shrink O’Mobile

Remem­ber Shrink O’Matic, the “oh, so easy to use” image shrinker for Win­dows, Mac and Linux? Intro­duc­ing Shrink O’Mobile, the “oh, so easy to use” image shrinker for Android!

Because cam­eras on phones take big pic­tures and because you might want to send smaller/lighter ver­sions, Shrink O’Mobile is here to help out. Just launch the app, choose the way you want your image to be shrunk, pick your image and BOOM! Your fresh, smaller, new ver­sion is instantly stored in your cam­era roll. Easy as pie.

And did I men­tion the app is free? It is.

Okr – Story of a failure

Some projects become real, oth­ers never see the light of day. This one is more of an abortion.

Six month ago I’ve been con­tacted by an archi­tec­tural firm to pro­vide some con­sult­ing on a project of theirs (I’m not going to name names, you’ll under­stand why). The goal was to find ideas to make a building’s front more inter­est­ing. The build­ing being a place to help and pro­mote Hip-Hop culture.

So I started work­ing on it and came up with ideas and con­cepts. The archi­tect I was in con­tact with seemed pretty happy with it and every­thing was look­ing good.

Until I no longer received any answer to my e-mails… Our last inter­ac­tion is now 5 month old and I think time has come to mourn. What I came up with can be inter­est­ing and since it involves an Open­Source project, here are a few bits about it.

At that time I was dis­cov­er­ing  GML (Graf­fiti Markup Lan­guage) and Evan Roth’s work. Bor­deaux hosted Les Grandes Tra­ver­sées and all of this really inspired me. So I thought of a mash-up between GML’s #000000book (black book, open archive of GML tags), a player of my own (Okr), the build­ing itself and Twit­ter. Here’s the doc­u­ment I pre­sented to explain what I had in mind.

The steps are:

  1. Cre­at­ing and send­ing a graffiti;
  2. Receiv­ing data;
  3. Con­vert­ing it to an image;
  4. Pro­ject­ing it on the building’s front;
  5. Photo-shooting of the front;
  6. Send­ing to Twitter;
  7. Online con­sul­ta­tion.

After a few e-mails with Jamie Wilkin­son (heads up!) I started work­ing on the core classes writ­ing GMLPlayer and GML­Cre­ator. The goal was to pro­vide both a way to dis­play tags and to create/upload them. I then built a UI around all that (a Flex one, after notic­ing Min­i­mal Comps didn’t work the way I expected).

iframe: <a href=""></a>

Note: you’ll also find the app on its ded­i­cated page. Try search­ing for “dasp” or “hello world” for exam­ple and play with the set­tings (the 3 top sliders).

Unfor­tu­nately it is only after cre­at­ing all this that I real­ized the project would never become real… So I sim­ply stopped work­ing on it. I am well aware that some parts of the code is a bit raw and could be opti­mized and I haven’t built the creation/upload fea­ture into the UI yet. Don’t know if I will, but the project is Open­Source so feel free to give it a spin! I also share my ini­tial attempt and a pixel ver­sion in case you’re interested.

Pretty happy that — even if not fea­ture com­plete — Okr made it to the GML project gallery, yay!

And just because a project will never see the light of day doesn’t mean it doesn’t need a proper logo, right?

AIR Application Updater: switch to the 2.5 namespace

I just wasted a few hours on under­stand­ing how to update an AIR app from the 2.0 name­space (or ear­lier) to the brand new 2.5 one. As you may know, two new tags have been intro­duced (“ver­sion­Num­ber” and “ver­sion­La­bel”) to replace the old “ver­sion” one.

To avoid break­ing things you have to cre­ate an inter­me­di­ary app ver­sion that will smoothly switch from 2.0 to 2.5, here’s what you can read on the release notes page:

In order to be able to update from ver­sion 1 to ver­sion 2, an inter­me­di­ary update step must be added as fol­lows: appli­ca­tion ver­sion 1, pack­aged with AIR 2 and using the 2.0 name­space gets updated to: appli­ca­tion ver­sion 1.5, pack­aged with AIR 2.5 and using the 2.0 name­space. This ver­sion of the appli­ca­tion must include the ver­sion of the Appli­ca­tion Updater SWC/SWF included with the AIR 2.5 SDK. This gets updated to: appli­ca­tion ver­sion 2.0, pack­aged with AIR 2.5 and using the 2.5 namespace.

Where “appli­ca­tion 1.5″ is the inter­me­di­ary step.

All of this looks quite sim­ple but really it isn’t; or at least it wasn’t for me. To be really explicit here are my 3 appli­ca­tion descrip­tors and the update descrip­tor (ver­sion num­bers changed to match Adobe’s example).

Appli­ca­tion descrip­tor – Ver­sion 1 (pack­aged with AIR 2.0):

  1. <?xml version="1.0" encoding="utf-8" standalone="no" ?>
  2. <application xmlns="">
  3. (...)<version>1</version>(...)
  4. </application>

Appli­ca­tion descrip­tor – Ver­sion 1.5 (pack­aged with AIR 2.5):

  1. <?xml version="1.0" encoding="utf-8" standalone="no" ?>
  2. <application xmlns="">
  3. (...)<version>1.5</version>(...)
  4. </application>

Appli­ca­tion descrip­tor – Ver­sion 2 (pack­aged with AIR 2.5):

  1. <?xml version="1.0" encoding="utf-8" standalone="no" ?>
  2. <update xmlns="">
  3. (...)<versionNumber>2</versionNumber>(...)
  4. </update>

Update descrip­tor (PHP script receiv­ing the caller’s cur­rent ver­sion as “cur­rentVer­sion” GET variable):

  1. <?php
  2. header("Content-Type: text/xml; charset=utf-8");
  3. echo '<?xml version="1.0" encoding="utf-8"?>';
  4. $currentVersion=array_key_exists('currentVersion', $_GET) ? (float)$_GET['currentVersion'] : 1;
  5. $isNewNamespace=$currentVersion>=2;
  6. $ns=''.($isNewNamespace ? '2.5' : '1.0');
  7. $version=$currentVersion>=1.5 ? 2 : 1.5;
  8. $versionTag=$isNewNamespace ? 'versionNumber' : 'version';
  9. ?>
  10. <update xmlns="<?php echo $ns ?>">
  11. <<?php echo $versionTag ?>><?php echo $version ?></<?php echo $versionTag ?>>
  12. <url><?php echo $version ?>.air</url>
  13. </update>

Not that sim­ple, right? And this is not only annoy­ing to the devel­oper, but also to the end user. He will be noti­fied of an update from ver­sion 1 to 1.5 and when he’s done he’ll get prompted about the new-new ver­sion (2): bang, another update process.

If you’re curi­ous of how I send the app’s ver­sion to the update descrip­tor, here it is:

  1. _appUpdater.updateURL=''+App.getVersion();

The App class is avail­able in my as3bits repository.

A Golden Ratio Tool

iframe: <a href=""></a>

I wrote a quick and sim­ple golden ratio tool (ded­i­cated page). Basi­cally it helps you find “golden ratio neigh­bors” for a given num­ber: every num­ber in the list divided/multiplied by its neigh­bor = φ.

Pretty straight­for­ward but could come in handy. I’m aware it could be improved; if you have suggestions…
